The Space Shuttle usesaluminum metal and aluminum perchlorate in its reusable boosterrockets. The products of the reactionare aluminum oxide, aluminum chloride, nitrogen oxide gas, andsteam: 3 Al + 3NH4ClO4Al2O3 +AlCl3 + 3 NO + 6H2O so what mass of NH4ClO4 should be used in the fuel mixture for every KILOGRAM of Al?
